LIQUID-WEIGHING MACHINE.

To all whom it may concern.'

Be it known that I, RUrUs W. ENsLEY, a citizen of the United States, anda resident of Cory, in the county of Delta and State of Colorado, haveinvented a new and lmproved Liquid-Veighing Machine, of which thefollowing is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to provide a machine for filling cartons with heavy or viscous fluid; t0provide a machine for filling cartons, adapted to discontinue the flowof the liquid when the said cartons are lled; to provide a mechanism fordiscontinuing the flow from the reservoir of materials of the characterspecified when a prescribed quantity has been delivered therefrom; andto provide a machine of the character specied, the construction andarrangement whereof is simple and economical.

One embodiment of the present invention is disclosed in the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in all the views, and in which-Figure 1 is a side elevation of a machine constructed and arranged inaccordance with the present invent-ion, shown in conjunction with a tankfor holding honey; Fig. 2 is a side elevation, on an enlarged scale, ofthe head for supporting the weighing scales and the mechanism connectedtherewith for operating the fluid controlling device; Fig. 3 is avertical cross section taken on the line 3 3 in Fig. 2; Fig. 4: is adetail view, on an enlarged scale and in vertical section, of a triggermechanism for releasing the iiuid controlling devices, the dotted linesin said figure representing a bolt are used to show the position of saidbolt with reference to the steel yard, the position of said bolt beingin front of the section line 3 3, on which line the said section istaken; and Fig. 5 is a vertical section taken on t-he line 5 5 in Fig.3.

One of the purposes for which the present invention is employed is todeliver from a reservoir, or storage receptacle, honey after the samehas been extracted or separated from the comb. rlhe honey is of a heavyor viscous consistency, flowing at a rate which consumes more time onthe part of an attendant than it is desired to give. To avoid this lossof time, and to accurately measure Specification of Letters Patent.Patented Apr. 25, 1911. Application filed July 19, 1910.

Serial No. 572,674.

the quantity of material delivered, is the particular purpose of thepresent embodiment of the invention.

In the drawings the numeral 6 is employed to designate a tank in whichthe honey is stored after being extracted or separated from the comb.The tank is provided in the usual manner with a spout opening 7 to closewhich a gate valve 8 is pivoted at 9. The gate valve 8 is provided withan extended end or handle 10 by which the said valve is manipulated toclose and open the passage in the spout 7. It is the object of thehereinafter described machine to close the gate valve S when apredetermined quantity of honey has been drawn from the tank 6.

To measure the quantity by liquid measure when using the machine hereinshown and described, a balancing scale employing a steel yard 11 isused. Attached and suspended from the steel yard 11, by means of foursupporting rods 12, 12, is a scales platform 13. The desired quantity ofhoney is drawn into a carton A, (as for instance a five gallon can), andthe can, as filled, is placed upon the platform 13 and weighed byshifting the movable weight 14 on the steel yard until the said steelyard is balanced or depressed on the platform supporting side. Eachsubsequent carton A, when so filled, will thus tip the steel yard 11. Byutilizing the tipping action of the steel yard 11 to release thesuspended weight 15, l permit the same to strike upon the handle 10 andclose the passage of the spout 7.

The steel yard is suspended from a hanger rod 16, the lower end whereofis bifurcated and provided with the usual knife edge balancing pivot.Set out from the steel yard 11, on the platform suspended side thereof,is a second knife edge pivot to which the eyes 17 of the rods 12, 12 areconnected. The hanger rod 1G is mounted in an open rectilinear frame 13.The frame 18 is supported in elevated position upon a tripod formed bythe legs 19, 19.

The frame 18 is provided with a vertical plate 20, which is perforatedto form passages for the extension of a trigger grip 21 and a tail piece22. The trigger grip 21 is extended from a trigger 23, which ispivotally mounted on pins 24E in the plate 20. The trigger 23 isprovided with a notched end 25. The notched end 25 is adapted to assumelocked relation with the notched end 26 of a trip 27, from which thesaid tail piece 22 is extended. The trip 27 is normally maintained invertical position by a leaf spring 28, the end of which extends into anopening 29 formed in the end of the trip 27. The trigger 23 is providedwith a leaf spring 30, the free end whereof rests in a notch 31. Thenotch 31 is closely disposed with reference to the pins 24. Theoperation of the spring 30, when unrestrained by the trip 27, is tothrow the trigger 23 to the position shown in Fig. Ll of the drawings.In thus moving the trigger a spring pawl is deflected from engagementwith a ratchet wheel In its normal or balanced position the steel yard11 rests under the tail piece 22 of the trip 27, as shown in Figs. 3 and11- of the drawings. lVhen now in the operation of the machine thecarton A becomes tilled so that the weight of the filled cartondepresses the platform supporting end of the steel yard 11, the free endof the said steel yard rises and lifts the tail piece 22, throwing thetrip 27, and thereby releasing the trigger 23. rl`he release of thetrigger 23 by the trip 27, as above stated, permits the spring 30 torotate the trigger 23 until the elongated arm thereof removes the springpawl 32 from engagement with the ratchet wheel The trip and triggerremain in this position until the machine is reset.

The trigger 23 and trip 27 are reset manually. The attendant7 havingremoved the carton A and replaced the same with an empty carton, theplatform 13 is raised by the weight 11.1-, removing the free end of thesteel yard 11 from contact with the tail piece 22 of the trip 27. Inthis position of the trip 27 the trigger grip 21 is engaged by thelinger of the attendant and lifted. In thus lifting the grip 21 the endof the trigger 23 having the notch 25 is placed in engaged relation withthe end of the trip 27 having' the notch 2G, the spring 30 having beenforced to yield to the hand pressure to allow for thus seat-ing thetrigger. The spring pawl being thus released resumes its position toride upon the teeth of the ratchet wheel 33.

As above stated, when the steel yard 11 is tipped by the weight on theplatform 13, 'the weight 15 is permitted to drop on the handle 10 of thegate valve 8, thereby closing the same. The weight 15 is suspended froma cable 34, which is reeved over a pulley 35 and wound upon a drum 3Gextended from the side of the frame 13. The pulley is extended above theframe 13 on a short mast 37.

Between each operation it becomes neces sary to raise the weight 15.'Ihis is accomplished by rotating a shaft 33 by means of manuallyoperated. crank handle 3S). The winding of the cable 34, as abovestated, occurs after the trigger 23 has been set, and

when` the pawl 32 is engaged with lthe teeth of the ratchet wheel 33.'ihe ratchet wheel 33 is tixedly mounted on the shaft 33 carryingl thedrum 3G.

It is Yto apprise the attendant of the operation of the machine` and ofthe fact that the carton has been filled, that a bell Ll() is mounted onthe frame 13. Fixedly mounted on 'the shaft 33 is a arm 'l-l. Pivotallyand loosely mounted on the end of thc arm 'll. is a swinging hammer 112,the olli e of which is to strike the bell i0 with each rotation of theshaft 33, thus sounding an alarm, calling attention to the condition ofthe machine and tank `When this alarm is thus sounded it is the duty ofthe attendant' to replace theI filled with an empty carton A. to re-setthe trigger 23, to rewind the cable 3i suspending the weight 15, andthen to open the gate valve 3 to permit the material to tlow from thetank (S into the new carton. In this position. he may leave the machineuntil the carton, becoming filled, the operation above described isrepeated, the alarm apprising him of the need of again renewing thecarton.

During the periods when the cartons are being loaded upon or unloadedfrom the platform 13, the stcelyard is locked in lixed position by adrop latch 43. lVhen the loaded carton is placed in position the latchis raised by lifting the handle dat, which permits the steelyard to risewhen the carton is heavy enough to overbalance it.

To limit the rise of the steelyard, I have provided a stop bolt rlChebolt 45 passed through the supporting frame just above the lowered orset position of the trigger 22, or in a position to receive and hold thesteelyr rd after the said trigger has been tripped, as shown by dottedlines in vFig. il; of the drawings.
